If you cast your mind back to December and the run-up to the Christmas number one slot in the UK charts, you might recall Justin Bieber being sound for once in his life.

The pop star encouraged people to buy a charity single by the NHS Choir, instead of his own single 'Love Yourself', saying 'for one week it's OK not to be #1'.

The NHS Choir's mash-up of 'Bridge Over Troubled Water' and Coldplay's 'Fix You' did indeed go to number one, and Bieber was on hand to present them with their official award at an event in London yesterday.

He told OfficialCharts.com: "“I was honored to meet everyone from the choir and I’m really happy that they got their #1."
